I reformatted my hard drive to install a copy of Windows 7 Ultimate, 64bit (I had Windows 7 Premium, 64bit before) and the installation ran just fine. After the installation, it boots up to what I guess is the desktop, waits a few moments, then just reboots. Every time before it boots it goes to the "Windows is loading files..." screen. I also tried 32bit, but got the same results. If you need more information, just ask and I'll be glad to provide it for you. A USB stick was used to install.
Edit: I just looked through all the forums and I might of posted this in the wrong section, deeply sorry if that is the case.
